SPECIFICATION forming part of Letters Patent No. 517,238, dated March 2'?, i894.

Application filed April 15, 1393. Serial No. {170,454. (No model.)

To @ZZ whom it may concern:

Be it known that I, GEORGE RHODEN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented'certain new and useful Improvements inSmoke-Consumersof which Ehe following is a full, clear, and exact descripion.

My invention consists of a parti-wall, which divides the furnace under a boiler into two chambers, and a wall back of the ordinary bridge-wall, with Iiues and openings in said walls as hereinafter fully described.

The object of my improvement is to provide a means for consuming and utilizing as fuel the carbonaceous properties and infiammable gases of which smoke is largely com posed and rendering said smoke comparatively free from all impurities, when it reaches the outside atmosphere. By actual experiment, I have demonstrated that a positive economy in fuel and awhite smoke, at the top of the'chimney, result from the use of my consumer.

That my invention may be seen and fully understood by others, reference will be had to the following specification and annexed drawings forming a part thereof in which- Figure 1 is a longitudinal, vertical section on line a, c, Fig. 2; Fig. 2, a longitudinal, horizontal section on line h, b, Fig. l; Fig. 3, a transverse, vertical section on line c, c, Fig. 1, looking toward the rear; Fig. 4, a transverse, vertical section on line ol, d, Fig. l, looking toward the front; Fig. 5, a transverse, vertical section on line e, e, Fig. 1, looking toward the front; Fig. 6, a sectional view of two of the bricks used in the construction of the parti-wall, showing the tlues therein, and Fig. 7, an end view of the same.

Similar letters of reference designate like parts in the drawings and specification.

Below the front end of the boiler A, Figs. 1, 3, 4 and 5, is a furnace divided, by the parti-wall B, Figs. l, 2, 3 and t, into the chambers C and C. The parti-wall B extends vertically from the bottom of the boiler A to the` iioor D, of the furnace, and horizontally from the front D', of said furnace, to the bridgewall E, Figs. l, 2, 3 and 4.. Each of the chambers C and C is provided with the grate F, Figs. 1, 2 and 3.

' Back of the boilerA is the chimney G having the flue G'.

A short distance behind the bridge-wall E is the wall H, Figs. l, 2, 3 and 5, having the opening H', Figs. l, 2 and 5. The wall H eX- tends vertically from the iioor D to the boiler A and connects the sides I, I of the furnace inclosure.v Above the bottom of the boiler A, the wall H may be thinner than below, as indicated at H2, Fig. 5.

Against the sides I, I and between the ends of the bridge-wall E and the wall H, but on a level with the top of said bridge-wall, are the connecting-walls J, J, Figs. 1, 2 and 4, forming, with the bridge-wall and the wall H, the y flue J' open at the top.

In the bridge-wall E and the connectingwalls J, J are the flues K, K, Figs. 1,2, 3 and 4, which open, at one end, below the gratesF each side of the parti-wall B and, at the other, into the ue J near the top thereof. The flue L, best shown in Fig. 3, is located in the parti-wall E, near the front, and opens, at the base, into the chambers C, and C. The upper part of` the iiue L, is connected with the flue J' by one or more horizontal fines M, Figs. l, 2, 3 and 11.

Between the grates F and the top of the bridge-wall E, the parti-wall B is constructed of the bricks N, Figs. 6 and 7, having the holes or flues M therein. The bricks N have a groove extending through the-center of the upper and under edges thereof and when two of said bricks are brought together, as shown in Figs. 6 and 7, the flue M lis formed. It will now be readily seen that air received into the iiue I., in the parti-wall B, in its passage through the fines M, will become super-heated before it` enters the iiue J', while a portion of the hot air below the grates F, enters said Hue J through the flues KI,'K. Since the wall H is built tight to the boiler, the smoke arising from the re on the grates F is drawn over the bridge-wall E down into the flue J', by the draft which passes through the opening H', in said wall H. In the flue J' the smoke commingles with the super-heated air from the fines M and K, K and the larger part or all of said smoke is thereby consumed.' Any portion of the smoke not destroyed, in the manner above described, finds its way through the ordinary channels to the liuc G', of the IOC chimney G, and passes off. The best results are produced when the fire on one grate F is at a red heat and the other black with fresh coal, since, by alternating in this way, sufficient heat will be eliminated from the bright re t0 consume the smoke arising from the fire in the other chamber.

By constructing the parti-Wall B, between the grates and the top of the bridge-Wall E, of the bricks N a saving of expense results, for said bricks having the fines M therein willldnot burn out so quickly as they would if so 1 A particular advantage of my smoke c0nsumer lies in the fact that it may be applied to any furnace and boiler with slight cost, when compared with other devices for a similar purpose.

What I claim as my invention, and desire to secure by Letters Patent, is-

In a smoke consumer, a furnace below a boiler divided into two chambers by a partiwall having iues therein opening, at the front, each side below the grates, and at the rear, into the iiue J near the top, in combination with the wall l-I having the opening l1', and the connecting-walls J, J forming
